Answer:
Opinion
Explanation:
To best answer this question, you need to make sure you understand the difference between a fact and an opinion.
A fact something that is true, regardless of what anyone thinks of it. For example, "George Washington was the first president of the United States" is a fact regardless of anyone's thoughts about the matter because it's true.
An opinion is someone's input on a matter that is not necessarily true. For example, "George Washington was a terrible president" is an opinion because it's not something that can be proven as true. Many people may also think he was an amazing president, and that idea is an opinion as well.
The sentence, "Donnie Darko was a little scary" is an opinion because it's not something that is necessarily true. Some people may think Donnie Darko was not scary at all. It's just a personal idea about the movie that differs from person to person.
